Abstract :

In this paper, a peculiar design method for determining the optimal proportional –integral-derivative (PID) controller parameters in the AVR system using the particle swarm optimization (PSO) algorithm is presented. The use of PSO method to search productively the optimal PID controller parameters in an automatic voltage regulator (AVR) system is exposed in detail in this paper. The suggested approach had superior features, like stable convergence characteristic, easy implementations and good computational efficiency. Fast tuning of optimum PID controller parameters turns out high-quality solution. A time-domain performance criterion function was also defined, in order to collaborate estimating the performance of the PSO-PID controller. Compare with the genetic algorithm (GA) and Ziegler-Nichols methods, this method was absolutely more efficient and robust in improving the step response of an AVR system
